Unfortunately the login-process uses some sort of challenge-response mechanism (GET CHALLENGE command followed by EXTERNAL AUTH) So far I have absolutely no idea how to compute the response from a given challenge. I do know where the certs and keys are, and I do know all APDUs that are necessary. So the response-computation is the only missing information.
for this you need to extract the secret key used for the MAC generation (I assume a symmetric key is used here) from the library ;-) The rest shouldn't be too difficult (although opensc doesn't really support the various EXT. AUTHENTICATE variants at the moment). Getting the key could be the fun part. Btw: it is a windows or linux binary ?
